The Dangers of Exposure to Asbestos
Before it was banned, asbestos was still used in a variety of commercial products. Studies have shown that exposure to asbestos can cause cancer and other health problems.
It is difficult to tell by looking at something whether it contains asbestos. Also, you cannot smell or taste it. Asbestos can only be detected when the materials that contain it are broken or drilled.
Chrysotile
At its peak, chrysotile accounted for 99% of the asbestos produced. It was utilized in a variety of industries, including construction insulation, fireproofing, and insulation. If workers are exposed to asbestos, they are likely to develop mesothelioma or other asbestos-related illnesses. Thankfully, the use this harmful mineral has diminished dramatically since mesothelioma awareness began to increase in the 1960's. However, traces of it can still be found in products that we use in the present.
Chrysotile is safe to use when you have a thorough safety and handling program in place. Personnel handling chrysotile aren't exposed to an undue amount of risk at the current limits of exposure. Lung fibrosis, lung cancer and mesothelioma have been strongly associated with breathing in airborne respirable fibres. This has been proven to be true for both the intensity (dose) and time span of exposure.
In one study mortality rates were compared between a facility which used largely Chrysotile for the production of friction materials and the national death rate. The study concluded that, after 40 years of processing low levels of chrysotile there was no significant rise in mortality in this factory.
Chrysotile fibres are typically shorter than other types of asbestos. They can penetrate the lungs, and enter the bloodstream. This makes them more likely to cause health effects than fibres with longer lengths.
It is very difficult for chrysotile fibres to be in the air or pose a health risk when mixed with cement. Fibre cement products are extensively used throughout the world particularly in buildings such as schools and hospitals.
Research has shown that chrysotile is less likely to cause disease than amphibole asbestos such as crocidolite and amosite. These amphibole kinds have been the main source of mesothelioma, as well as other asbestos-related diseases. When chrysotile is mixed in with cement, it forms an extremely durable and flexible building product that is able to withstand severe conditions in the weather and other environmental dangers. It is also easy to clean after use. sanger asbestos attorney fibres can be easily removed by a professional and then safely eliminated.
Amosite
Asbestos is a class of fibrous silicates found in certain types of rock formations. It is divided into six groups: amphibole (serpentine), Tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.
Asbestos minerals are made up of thin, long fibers that vary in length from very fine to wide and straight to curled. They can be found in nature as bundles or individual fibrils. Asbestos can also be found in a powder form (talc), or combined with other minerals in order to create vermiculite or talcum powder. They are extensively used as consumer products, such as baby powder, cosmetics and facial powder.
The heaviest use of asbestos occurred in the early two-thirds of the 20th century when it was utilized in insulation, shipbuilding, fireproofing and other construction materials. Most occupational exposures were to asbestos fibres borne by air, but some workers were exposed to vermiculite or talc that was contaminated and to pieces of asbestos-bearing rocks (ATSDR 2001). Exposures varied according to industry, time and geographic location.
The exposure to asbestos in the workplace is mainly because of inhalation. However there are workers who have been exposed via skin contact or through eating foods contaminated with asbestos. Asbestos is only present in the environment from the natural weathering of mined ore and the degradation of contaminated products such as insulation, car brakes and clutches, and floor and ceiling tiles.
There is evidence to suggest that non-commercial amphibole fibres may also be carcinogenic. These are fibres don't form the tightly weaved fibrils of serpentine and amphibole minerals, but instead are loose, flexible and needle-like. These fibers are found in the mountains and cliffs in a variety of countries.
Luverne asbestos can be found in the environment as airborne particles, but it can also be absorbed into soil and water. This occurs both from natural (weathering and erosion of asbestos-bearing rocks) and anthropogenic (disintegration and disposal of asbestos-containing materials in landfill sites) sources. Asbestos contamination of ground and surface water is largely associated with natural weathering, but has also been caused by anthropogenic activities such as milling and mining demolition and dispersal asbestos-containing material and the disposal of contaminated dumping soil in landfills (ATSDR 2001). Airborne asbestos fibres are the primary cause of illness among people exposed to asbestos during their job.
Crocidolite
Inhalation exposure is the most commonly used method of exposure to asbestos fibres. These fibres can get into the lungs and show Low asbestos cause serious health problems. These include asbestosis and mesothelioma. Exposure to fibers can occur in other ways as well, such as contact with contaminated clothing or materials. This type of exposure is especially dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite fibers are less dense and more fragile which makes them more difficult to breathe. They also can get deeper within lung tissues. It has been linked to a larger number of mesothelioma related cases than any other form of asbestos.
The six major types are chrysotile as well as amosite. The most commonly used asbestos types are epoxiemite as well as chrysotile which together comprise the majority of commercial asbestos employed. The other four asbestos types aren't as widespread, but they can still be present in older structures. They aren't as hazardous as amosite or chrysotile, but they can still be a danger when mixed with other minerals, or when mined near other naturally occurring mineral deposits like vermiculite and talc.
Several studies have found an association between exposure to rockdale asbestos and stomach cancer. A number of studies have confirmed that asbestos exposure is linked to stomach. However the evidence is not conclusive. Some researchers have reported an SMR (standardized mortality ratio) of 1.5 (95% of the time CI: 0.7-3.6) for all asbestos-related workers, while others have reported an SMR of 1.24 (95 percent C.I. 0.76-2.5) for workers in chrysotile mines and mills.
IARC The IARC, also known as the International Agency for Research on Cancer has classified all kinds of asbestos carcinogenic. All asbestos types can cause mesothelioma, however, the risk is dependent on the amount of exposure is taken, what type of asbestos is involved and the length of time that exposure lasts. IARC has stated that the best option for people is to avoid all forms of asbestos. However, if a person has been exposed to asbestos in the past and suffer from an illness such as mesothelioma or other respiratory diseases, they should seek guidance from their GP or NHS 111.
Amphibole
Amphiboles comprise a variety of minerals that can form needle-like or prism-like crystals. They are an inosilicate mineral that is composed of two chains of SiO4 molecules. They have a monoclinic arrangement of crystals, however certain crystals have an orthorhombic form. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains consist of (Si,Al)O4 Tetrahedrons which are connected in rings of six. The tetrahedrons are separated from each other by strips of octahedral sites.
Amphibole minerals can be found in metamorphic and igneous rocks. They are usually dark-colored and are hard. Due to their similarity of hardness and color, they may be difficult for some people to distinguish from pyroxenes. They also have a comparable Cleavage. However their chemistry allows an array of compositions. The different mineral groups in amphibole can be identified by their chemical compositions and crystal structures.
The five asbestos types that belong to the amphibole group include amosite, anthophyllite and chrysotile, crocidolite, and actinolite. Each kind of asbestos has distinct characteristics. The most dangerous form of asbestos, crocidolite is made up of sharp fibers that are easy to breathe into the lung. Anthophyllite is yellowish to brown in color and is made up of iron and magnesium. This kind of material was used to create cement and insulation materials.
Amphiboles are a challenge to analyze due to their complex chemical structure and numerous substitutions. A detailed analysis of the composition of amphibole mineral requires specialized methods. EDS, WDS and XRD are the most widely used methods for identifying amphiboles. However, these methods can only provide approximate identifications. These techniques, for example cannot differentiate between magnesio-hornblende and hastingsite. These techniques also cannot distinguish between ferro-hornblende as well as pargasite.
